Desktop application development begins with selecting the appropriate platform approach: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution method. A clearly defined MVP and an early mock-up help validate workflows, performance requirements, and the overall UX on real machines.

As the product evolves, reliability, updates, and packaging become essential. Careful management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains dependable in daily use, while an update system and crash reporting facilitate long-term support.
